LM224KDG4

Overview

The LM224KDG4 is a quad operational amplifier manufactured by Texas Instruments, belonging to the LM224 series. It features four independent high-gain amplifiers within a single package. The device operates with a supply voltage range of 3 V to 32 V or dual supplies from ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 1.2 MHz and a slew rate of 500 mV/µs. Input characteristics specify an input offset voltage of 5 mV and an input bias current of 150 nA. The output can source up to 20 mA per channel. The component is housed in a 14-pin SOIC package and supports surface-mount installation. It functions without a shutdown mode and maintains operation across a temperature range of -25°C to +85°C.

Feature Summary

• Integrates four independent high-gain operational amplifiers for multi-channel signal processing
• Supports wide single or dual power supply voltage ranges for flexible system integration
• Provides rail-to-rail input capability to maximize dynamic range
• Delivers sufficient drive current for direct interfacing with loads

Applications

• General-purpose analog signal conditioning circuits
• Transducer amplification interfaces
• DC gain blocks in measurement systems
• Voltage comparators in control logic

Procurement Notes

Verify the specific suffix 'DG4' against the manufacturer's latest documentation to confirm compliance status and pinout compatibility. Ensure the ordering information matches the required package style and thermal specifications. Cross-reference the datasheet revision history for any updates regarding mechanical dimensions or electrical limits before finalizing procurement.

Selection Notes

Select this component when a quad amplifier configuration is required within a compact surface-mount footprint. Consider the 1.2 MHz bandwidth and 500 mV/µs slew rate for applications requiring moderate speed. Evaluate the 5 mV input offset voltage against precision requirements. Confirm that the 20 mA output current meets load driving needs without external buffering.

Part Context

This part belongs to the LMx24 family of quad operational amplifiers produced by Texas Instruments. The LM224 variant typically denotes commercial or industrial grade performance compared to the military-grade LM124 or automotive-grade LM324. The 'G4' suffix indicates lead-free construction compliant with RoHS standards. The 'D' designation specifies the SOIC package type.
